Incidentally, apart from this unpleasant little episode, the camera has been very pleasant to use. Better than the K5??? - Slightly but not a great deal. I'd describe it as easier to live with. - It focuses better, it exposes better and the films turn out generally better. There's no improvement in noise levels. The extra definition is barely noticeable BUT it's definitely a slightly more endearing camera. I sold the K7 but kept the K5. (Basically as a backup that is virtually the same).
